To be clear, we have a strong commitment to preserving compatibility with legacy web pages, even webpages written using this undesirable behavior (caller-syntax). As such we will be keeping the caller behavior in our "classic" rendering modes until such a time as we can prove with good data that removing support for it will have inconsequential side-effects on compatibility. The above sentiment mentioned regarding removing support was in our IE9 or later rendering mode.
